Cervical Vertebrae Overview. The cervical spine is made up of 7 vertebrae. The first 2, C1 and C2, are highly specialized and are given unique names: atlas and axis, respectively. C3-C7 are more classic vertebrae, having a body, pedicles, laminae, spinous processes, and facet joints.

Spine Basics The spine itself has three main segments: the cervical spine, the thoracic spine, and the lumbar spine. The cervical is the upper part of the spine, made up of seven vertebrae (bones). The thoracic is the center portion of the spine, consisting of 12 vertebrae. The lower portion of the spine is called the lumbar spine.

Seven vertebrae make up the cervical spine with eight pairs of cervical nerves.

Anatomy of the Human Spine Vertebrae are the 33 individual bones that interlock with each other to form the spinal column. The vertebrae are numbered and divided into regions: cervical, thoracic, lumbar, sacrum, and coccyx (Fig. 2). Only the top 24 bones are moveable; the vertebrae of the sacrum and coccyx are fused. The vertebrae in each region have unique features that help them perform their main functions. Cervical (neck) - the main function of the cervical spine is to support the weight of the head (about 10 pounds).

Vertebral column Vertebrae are defined by the regions of the vertebral column that they occur in. Cervical vertebrae are those in the neck area. With the exception of the two sloth genera (Choloepus and Bradypus) and the manatee genus, (Trichechus), all mammals have seven cervical vertebrae.t is commonly called the spine, or simply backbone. The articulating vertebrae are grouped into their regions; there are seven cervical vertebrae of the neck (C1 to C7); twelve thoracic vertebrae of the thorax (T1 to T12); and five lumbar vertebrae of the lower back above the pelvis (L1 to L5).

- Mammals - usually 7 cervical vertebrae. Reptiles, birds, & mammals - 1st two cervical vertebrae are modified & called the atlas & axis. atlas - 1st cervical vertebra; ring-like (most of centrum gone); provides 'cradle' in which skull can 'rock' (as when nodding 'yes') axis - 2nd cervical vertebra.

Degenerative Cervical Spine Disorders There are seven cervical bones in the spine. Known as vertebrae, they can be likened to the cars of a passenger train. The cars of the train, by themselves, are stiff with no ability to bend. Each car (ie, vertebra) is joined to its neighbor by a joint. The joint allows motion between the cars.

Chapter 39: The vertebral column The vertebral column usually consists of 33 vertebrae: 24 presacral vertebrae (7 cervical, 12 thoracic, and 5 lumbar) followed by the sacrum (5 fused sacral vertebrae) and the coccyx (4 frequently fused coccygeal vertebrae).The 24 presacral vertebrae allow movement and hence render the vertebral column flexible.igure legends.

Anatomy Your spine is made up of 24 bones, called vertebrae, that are stacked on top of one another. These bones connect to create a canal that protects the spinal cord. The seven small vertebrae that begin at the base of the skull and form the neck comprise the cervical spine.

Seventh cervical vertebra In humans, cervical vertebrae are the smallest of the true vertebrae, and can be readily distinguished from those of the thoracic or lumbar regions by the presence of a foramen (hole) in each transverse process, through which the vertebral artery passes. The remainder of this article focuses upon human anatomy.

Vertebra of the Neck Together, the vertebrae support the skull, move the spine, and protect the spinal cord, a bundle of nerves connected to the brain. All seven cervical vertebrae are numbered. The C1, the first vertebra in the column (closest to the skull), is also known as the atlas. The C2, the vertebra below it, is also known as the axis. The “C” stands for “cervical.”

Vertebral column The human vertebral column consists of 33 vertebrae. These are divided into different regions, which correspond to the curves of the spinal column. These regions are called the cervical spine, thoracic spine, lumbar spine, sacrum and coccyx. There are a total of 33 vertebrae in the vertebral column. The articulating vertebrae are named according to their region of the spine. There are seven cervical vertebrae, twelve thoracic vertebrae and five lumbar vertebrae. The number of vertebrae in a region can vary but overall the number remains the same.

The Cervical Spine The cervical spine is the most superior portion of the vertebral column, lying between the cranium and the thoracic vertebrae. It consists of seven distinct vertebrae, two of which are given unique names: 1  The first cervical vertebrae (C1) is known as the a tlas. 2  The second cervical vertebrae (C2) is known as the a xis.

Cervical Spine Anatomy The cervical spine contains 7 vertebral bodies C1 (atlas) C2 (axis) C1 to C7 have a transverse foramen. vertebral artery travels through transverse foramen of C1 to C6. C2 to C6 have bifid spinous process. C7 despite having a transverse foramen, the vertebral artery does NOT travel through it in the majority of individuals.

- The cervical spine refers to the uppermost portion of your backbone, which supports your head. Seven of the body's 24 spine bones, or vertebrae, make up the cervical spine. Four of the cervical spine bones are considered typical vertebrae.The remaining atypical cervical vertebrae are the atlas, axis and 7th cervical vertebra. Each of these bones has a distinctive structure and specialized function.eventh Cervical Vertebra. The 7th cervical vertebra is also considered atypical. It is actually quite similar in structure to the typical segments, but with a few distinctions. The most apparent difference is that the spinous process -- the pointy projection on the back side of the vertebra -- is quite elongated.

How Many Vertebrae Do Humans Have? Quick Answer. Adult humans have about 24 vertebrae. Children are born with about 33 vertebrae, but as they grow, some of the bones fuse together. Vertebrae are the bones that make up the spinal column.

Cervical Discs There are six cervical discs and 23 total discs in the entire spinal column. Each cervical disc rests between the cervical vertebrae, acts as a shock absorber in the cervical spine and allows the neck to handle much stress.here are six cervical discs and 23 total discs in the entire spinal column.

- However, your feedback is important to us. The thoracic spinal vertebrae consist of 12 total vertebrae and are located between the cervical vertebrae (which begin at the base of the skull) and the lumbar spinal vertebrae. The second thoracic vertebra, or T2, is located directly below the first thoracic vertebra (T1).

Vertebrae in the Vertebral Column The cervical spine (the neck) has seven vertebral bodies, also called segments. The top two segments are unique: The first cervical segment (called the atlas) is a ring that does not have a vertebral body. This vertebra is named C1. The second vertebral body (called the axis), acts as a post that the first vertebral ring. Like the rest of the spine, the next five vertebral segments (named C3-C7) have three joints at each segment, including one disc in the front and paired facet joints in the back.

- Thoracic vertebrae: the basics. The spine is made up of five unique segments: the cervical spine (neck), the thoracic spine (upper and middle back), the lumbar spine (lower back), the sacral spine (lower back) and the coccyx (tailbone).
